Raspberry PI 2 Model B
During update firmware with this command

sudo apt-get update && sudo apt-get upgrade

How to solve?

thanks,
Arnaldo.

Don’t do it, it will break your Volumio installation

Just to clarify, sudo apt-get update should be ok, but sudo apt-get upgrade is very likely to break the optimised Volumio packages.

Ok, great!
